Buggy code:
public class Combo extends Composite { int visibleCount = 5 ; public static final int LIMIT ; boolean ignoreSelect ; public Combo ( Composite parent , int style ) { } public void add ( String string ) { } public void add ( String string , int index ) { } public void addModifyListener ( ModifyListener listener ) { } public void addSelectionListener ( SelectionListener listener ) { } public void addVerifyListener ( VerifyListener listener ) { } static int checkStyle ( int style ) { } protected void checkSubclass ( ) { } public void clearSelection ( ) { } public Point computeSize ( int wHint , int hHint , boolean changed ) { } public void copy ( ) { } void createHandle ( int index ) { } public void cut ( ) { } public void deselect ( int index ) { } public void deselectAll ( ) { } public String getItem ( int index ) { } public int getItemCount ( ) { } public int getItemHeight ( ) { } public String [ ] getItems ( ) { } String getNameText ( ) { } public int getOrientation ( ) { } public Point getSelection ( ) { } public int getSelectionIndex ( ) { } public String getText ( ) { } public int getTextHeight ( ) { } public int getTextLimit ( ) { } public int getVisibleItemCount ( ) { } void hookEvents ( ) { } public int indexOf ( String string ) { } public int indexOf ( String string , int start ) { } public void paste ( ) { } public void remove ( int index ) { } public void remove ( int start , int end ) { checkWidget ( ) ; if ( start > end ) return ; int [ ] argList = new int [ ] { OS .

Fix:
if ( ( argList [ 1 ] ) == ( ( end - start ) + 1 ) ) {
